About Wire and Cable

Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

Armored Building Cable with Uninsulated Ground Wire

Also known as AC cable, this cable has an uninsulated aluminum ground wire that's in constant contact with the aluminum armor, so it can be used for bonding and grounding. The uninsulated ground wire is not counted in the number of wires. The armor acts as conduit to protect the THHN building wires. It's often used along the exterior of walls to carry power to outlet boxes. All are flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material.

Flexible Metal (FMC) Conduit and Fittings

Make tight bends and protect wiring from being crushed. This corrugated conduit snakes around corners where rigid metal conduit won’t fit. For use indoors, it’s ideal for short connections or runs through walls in spaces that require both flexibility and durability.

Straight Electrical Box Connectors


Screw-Clamp × Threaded	Screw-Clamp × Snap-In	Push-In × Snap-In

Attach conduit to a knockout in an electrical box.

Zinc Alloy—A good option for light duty applications that don't require high strength. These fittings resist occasional exposure to moisture.
